What should you check for on pesticide labels before use?

When preparing to use a pesticide, it is essential to thoroughly review the label for several critical factors, ensuring not only effectiveness but also safety and compliance with regulations. Each of the elements mentioned in the choices plays a vital role in proper pesticide application.

Firstly, checking the expiration date is important because using a pesticide that is past its shelf life can lead to reduced efficacy and potential safety hazards. Products may degrade over time, especially if not stored properly.

Secondly, application rates are crucial for ensuring that the pesticide is used at the correct concentration. Using too little may not effectively control the target pest, while using too much can lead to damage to the environment, non-target organisms, or the application area itself. Adhering to specified application rates also ensures compliance with legal and regulatory requirements.

Lastly, safety instructions outline necessary precautions to protect applicators, bystanders, and the environment. This includes personal protective equipment (PPE), first aid instructions, and specific guidelines on how to handle the pesticide safely.

Considering these factors, it becomes clear that checking expiration dates, application rates, and safety instructions are all essential steps before using a pesticide, which makes selecting all of the options as the correct answer the most comprehensive and prudent choice.
